urlConnection.setRequestMethod("Get");
To this one
urlConnection.setRequestMethod("GET");

How to show coordinates-markers on Android App with Google Maps from XML file

I have an xml file with some places in it and their coordinates. I want to show those places on my android app on Google Maps as markers. I have already load the maps.
How could I do this? Any help would be so much appreciated, even if someone could explain it theoritically, as it seems I cant grasp its concept. Can someone help?
example of xml file(placesp.xml):
<placesp>
<placep>
<place_id>1</place_id>
<name>Place1</name>
<description>Place description 1</description>
<coordinates>;40.430224;21.559570</coordinates>
</placep>
<placep>
<place_id>2</place_id>
<name>Place2</name>
<description>Place description 2</description>
<coordinates>;40.423324;21.062439</coordinates>
</placep>
<placep>
<place_id>3</place_id>
<name>Place3</name>
<description>Place description 3</description>
<coordinates>;40.266952;21.238220</coordinates>
</placep>
</placesp>

Maybe you could use a HashMap to save the data.
You just create a new class like this:
public class Coordinates {
public static final HashMap<String, LatLng> COORDINATES = new HashMap<String, LatLng>();
static {
// Place1
COORDINATES.put("Place1", new LatLng(40.430224;21.559570));
}
}
You can access the data stored by the hashmap like this:
locationLatLng = new LatLng(Coordinates.COORDINATES.get("Place1").latitude,Coordinates.COORDINATES.get("Place1").longitude);
And then using this line in the class where you loaded the map to add the markers:
map.addMarker(new MarkerOptions().position(locationLatLng));
I am not really sure how to access data from the xml file, but in theory the logic is the same. You have to get a LatLng coordinate to tell the addMarker method where to put the marker, and thats actually it. I hope I could help you with this.

First you need to create a model class to hold the information for each place. I provide you a sample bellow: Place.class
public class Place {
private int placeId;
private String placeName;
private String placeDescription;
private double placeLongitude;
private double placeLatitude;
public Place() {
super();
}
public int getPlaceId() {
return placeId;
}
public void setPlaceId(final int placeId) {
this.placeId = placeId;
}
public String getPlaceName() {
return placeName;
}
public void setPlaceName(final String placeName) {
this.placeName = placeName;
}
public String getPlaceDescription() {
return placeDescription;
}
public void setPlaceDescription(final String placeDescription) {
this.placeDescription = placeDescription;
}
public double getPlaceLongitude() {
return placeLongitude;
}
public void setPlaceLongitude(final double placeLongitude) {
this.placeLongitude = placeLongitude;
}
public double getPlaceLatitude() {
return placeLatitude;
}
public void setPlaceLatitude(final double placeLatitude) {
this.placeLatitude = placeLatitude;
}
}
Next you will need a XML parser class to retrieve XML data to Place type list. You can use the following sample: PlaceXmlParser.class
public class PlaceXmlParser {
private static final String TAG = PlaceXmlParser.class.getSimpleName();
private static final String PLACE_ID = "place_id";
private static final String PLACE_NAME = "name";
private static final String PLACE_DESCRIPTION = "description";
private static final String PLACE_COORDINATES = "coordinates";
public PlaceXmlParser() {
super();
}
public List<Place> parsePlacesXml(final InputStream xmlStream) {
Place place = null;
final List<Place> placeList = new ArrayList<>();
try {
final XmlPullParserFactory xmlFactoryObject = XmlPullParserFactory.newInstance();
final XmlPullParser parser = xmlFactoryObject.newPullParser();
parser.setInput(xmlStream, null);
int event = parser.getEventType();
while (event != XmlPullParser.END_DOCUMENT) {
if (event == XmlPullParser.START_TAG) {
final String name = parser.getName();
switch (name) {
case PLACE_ID:
place = new Place();
setPlaceId(parser, place);
break;
case PLACE_NAME:
setPlaceName(parser, place);
break;
case PLACE_DESCRIPTION:
setPlaceDescription(parser, place);
break;
case PLACE_COORDINATES:
setPlaceLatLong(parser, place);
placeList.add(place);
break;
}
}
event = parser.next();
}
} catch (final XmlPullParserException e) {
Log.e(TAG, e.toString());
} catch (final IOException e) {
Log.e(TAG, e.toString());
}
return placeList;
}
private boolean areValidArgs(final XmlPullParser parser, final Place place) {
return null != parser && null != place;
}
private void setPlaceId(final XmlPullParser parser, final Place place) {
if (areValidArgs(parser, place)) {
final String placeId = getTagValue(parser);
place.setPlaceId(Integer.parseInt(placeId));
}
}
private void setPlaceName(final XmlPullParser parser, final Place place) {
if (areValidArgs(parser, place)) {
final String placeName = getTagValue(parser);
place.setPlaceName(placeName);
}
}
private void setPlaceDescription(final XmlPullParser parser, final Place place) {
if (areValidArgs(parser, place)) {
final String placeDescription = getTagValue(parser);
place.setPlaceDescription(placeDescription);
}
}
private void setPlaceLatLong(final XmlPullParser parser, final Place place) {
if (areValidArgs(parser, place)) {
final String[] latLong = getTagValue(parser).split(";");
if (3 == latLong.length) {
place.setPlaceLatitude(Double.parseDouble(latLong[1]));
place.setPlaceLongitude(Double.parseDouble(latLong[2]));
}
}
}
private String getTagValue(final XmlPullParser parser) {
String result = "";
try {
if (parser.next() == XmlPullParser.TEXT) {
result = parser.getText();
parser.nextTag();
}
} catch (final XmlPullParserException e) {
Log.e(TAG, e.toString());
} catch (final IOException e) {
Log.e(TAG, e.toString());
}
return result;
}
}
Finally, in you Google Map's activity, implement OnMapReadyCallback interface, override onMapReady method and add place markers to Google Map: MapActivity.class
public class MapActivity extends FragmentActivity implements OnMapReadyCallback {
private GoogleMap mMap;
private List<Place> placeList;
#Override
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_map);
this.placeList = getPlaceList();
}
#Override
public void onMapReady(final GoogleMap googleMap) {
this.mMap = googleMap;
addPlaceListMarkersToGoogleMap();
}
private void addPlaceListMarkersToGoogleMap() {
for (final Place place : this.placeList) {
final LatLong latLong = new LatLong(place.getPlaceLatitude(), place.getPlaceLongitude());
this.mMap.addMarker(new MarkerOptions().position(latLong).title(place.getPlaceName()));
}
}
private List<Place> getPlaceList() {
final String xmlString = "<placesp>" +
"<placep>" +
" <place_id>1</place_id>" +
" <name>Place1</name>" +
" <description>Place description 1</description>" +
" <coordinates>;40.430224;21.559570</coordinates>" +
"</placep>" +
"<placep>" +
" <place_id>2</place_id>" +
" <name>Place2</name>" +
" <description>Place description 2</description>" +
" <coordinates>;40.423324;21.062439</coordinates>" +
"</placep>" +
"<placep>" +
" <place_id>3</place_id>" +
" <name>Place3</name>" +
" <description>Place description 3</description>" +
" <coordinates>;40.266952;21.238220</coordinates>" +
"</placep>" +
"</placesp>";
final InputStream xmlStream = getXmlStream(xmlString);
final PlaceXmlParser parser = new PlaceXmlParser();
return parser.parsePlacesXml(xmlStream);
}
private InputStream getXmlStream(final String xmlString) {
InputStream xmlStream = null;
try {
xmlStream = new ByteArrayInputStream(xmlString.getBytes("UTF-8"));
} catch (final UnsupportedEncodingException e) {
e.printStackTrace();
}
return xmlStream;
}
}
Provided code works well for given XML sample, be aware of possible exceptions and handle it. Hope this help!

Fetching multiple rows from webservice and display it in android listview

i have this webservice:
[WebMethod]
public string findUserNameById(int Id)
{
return getStudent(Id);
}
public String getStudent(int id)
{
SqlConnection conn;
conn = Class1.ConnectionManager.GetConnection();
conn.Open();
SqlCommand newCmd = conn.CreateCommand();
newCmd.CommandType = CommandType.Text;
newCmd.CommandText = "select * from dbo.tblUser where Id=" + id + "";
SqlDataReader sdr = newCmd.ExecuteReader();
String address = null;
if (sdr.Read())
{
address = sdr.GetValue(0).ToString();
address += "," + sdr.GetValue(1).ToString();
address += "," + sdr.GetValue(2).ToString();
}
conn.Close();
return address;
}
which retrieve row values like this: Id, name, grade. and im calling this webservice from android application:
public class MainActivity extends AppCompatActivity {
private EditText editText;
private TextView textView;
private Handler mHandler= new Handler();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
editText = (EditText)findViewById(R.id.editText);
textView = (TextView)findViewById(R.id.textView);
}
public void getName(View v){
String inputId =editText.getText().toString();
//String[] params= new String[]{"10.0.2.2",inputId};
String[] params= new String[]{"192.168.1.17:90",inputId};
new MyAsyncTask().execute(params);
}
class MyAsyncTask extends AsyncTask<String, Void, String>
{
public String SOAP_ACTION="http://tempuri.org/findUserNameById";
public String OPERATION_NAME ="findUserNameById";
public String WSDL_TARGET_NAMESPACE ="http://tempuri.org/";
public String SOAP_ADDRESS;
private SoapObject request;
private HttpTransportSE httpTransport;
private SoapSerializationEnvelope envelop;
Object response= null;
#Override
protected String doInBackground(String... params) {
SOAP_ADDRESS="http://"+params[0]+"/myWebService.asmx";
request= new SoapObject(WSDL_TARGET_NAMESPACE,OPERATION_NAME);
PropertyInfo pi=new PropertyInfo();
pi.setName("Id");
pi.setValue(Integer.parseInt(params[1]));
pi.setType(Integer.class);
request.addProperty(pi);
pi= new PropertyInfo();
envelop= new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelop.dotNet=true;
envelop.setOutputSoapObject(request);
httpTransport=new HttpTransportSE(SOAP_ADDRESS);
try{
httpTransport.call(SOAP_ACTION,envelop);
response=envelop.getResponse();
}
catch (Exception e){
response=e.getMessage();
}
return response.toString();
}
#Override
protected void onPostExecute(final String result){
super.onPostExecute(result);
mHandler.post(new Runnable() {
#Override
public void run() {
textView.setText(result);
}
});
}
}
I want to fetch all of the rows and display it in a list view in the android, how to do it?
the query will be like : select * from dbo.tblUser
what should i change in the webservice? also what should i do in java for android?

try this code-
SoapObject response = (SoapObject) envelope.getResponse();
yourArray=new String[response.getPropertyCount()];
for(int i=0;i<response.getPropertyCount();i++){
Object property = response.getProperty(i);
if(property instanceof SoapObject){
SoapObject final_object = (SoapObject) property;
yourArray[i] = final_object.getProperty("YOUR_PROPERTY_NAME");
}
}
I would recommend that you declare your MainAsyncTask like this:
public class MainAsyncTask extends AsyncTask<String, Void, String[]> {
Then modify doInBackground to do all the processing that you are now doing in onPostExecute (except for the Toast part if any) and have it return the String[] (or null if there's an error). You can store the result code in an instance variable of MainAsyncTask and return null on error. Then onPostExecute has access to the same info that it does with your current code. Finally, if there is no error, just call a method in your main activity from onPostExecute to do the UI updates, passing it the String[] result.

Declare one POJO -
class AllocatedData{
String Id, name, grade;
getters and constructor
}
Code -
List<AllocatedData> list = new ArrayList<AllocatedData>();
if (responseLevel4 != null) {
for(int i = 0; i < responseLevel4.getPropertyCount(); i++){
responseLevel5 = (SoapObject) responseLevel4.getProperty(i);
Data allocated = new AllocatedData(checkStringProperty("Id"),checkStringProperty("name"),
checkStringProperty("grade"));
list.add(allocated);
}
}
}
Which function handles if property is Null
public String checkStringProperty(String propertyName){
if(responseLevel5.hasProperty(propertyName)){
return responseLevel5.getProperty(propertyName).toString();
} else {
return null;
}
}
But my Suggestion is use JSON reponse Or generate response in JSON.
I tried it before in Asp.net web services in which difficult to generated JSON. try WCF services
Link :- http://www.codeproject.com/Articles/167159/How-to-create-a-JSON-WCF-RESTful-Service-in-sec
By Using json you can parse directly by GSON liabrary this is very fast as compate to SOAP.
Gson gson = new Gson();
for (int i = 0; i < array.length(); i++) {
AllocatedData app = gson.fromJson(array.getJSONObject(i).toString(), AllocatedData .class);
list.add(app);
}

I would suggest you to create a Model Class which holds all the Property you need to send back
Public class Address{
public int grade;
public String name;
public String grade;
}
Create List<Address> addressList;
Iterate through the result set you get from database and in each iteration create a address object and put it in List and return List as response
Edit
Android Side reading from list you can refer this link
http://seesharpgears.blogspot.in/2010/10/web-service-that-returns-array-of.html
SERVICE SIDE
Instead of this Line
if (sdr.Read())
{
address = sdr.GetValue(0).ToString();
address += "," + sdr.GetValue(1).ToString();
address += "," + sdr.GetValue(2).ToString();
}
change it to
List<Address> addressList=new ArrayList<Address>();
while (sdr.Read())

android: 3 different markers have same data onclick, inner class

I have 3 markers in a map. I get marker data through a server and associate it through each marker. Due to data amount, I only get a subset of data for each marker (for development I have 3 markers, but there may be many more). So I associate an ID to each marker, and for the next activity, I get that ID and retrieve the complete data set for the next activity to be displayed.
Unfortunately all markers end up being associated with the same ID. What am I missing here?
Initially I was passing a final variable to the inner class in order to assign the ID. Finding this question: How to pass parameters to anonymous class? (kudos!) I introduced an initializer to the inner class, thinking the final attribute might have been the problem. But nope. Still getting the same ID on all markers.
private class Getter extends AsyncTask<String, Void, JSONArray> {
private Exception exception;
protected static final String TAG = "Getter";
protected JSONArray doInBackground(String... urls) {
try {
try {
//get JSON data from server
return json_objects.getJSONArray("objects");
} catch (JSONException jse) {
//more error handling
}
}catch(Exception e) {
this.exception = e;
return null;
}
}
protected void onPostExecute(JSONArray obj_arr) {
try {
if (this.exception != null) {
//some error handling
} else if (obj_arr != null) {
for (int i = 0; i < obj_arr.length(); i++) {
JSONObject obj = obj_arr.getJSONObject(i);
create_marker(obj);
}
}
} catch(JSONException jse) {
//error handling
}
}
private void create_marker(JSONObject obj) {
try {
JSONObject location = obj.getJSONObject("location");
double lat = location.getDouble("lat");
double lng = location.getDouble("lng");
String id = obj.getString("id");
LatLng pos = new LatLng(lat, lng);
mMap.addMarker(new MarkerOptions().position(
pos).title(obj.getString("name")).
mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
String local_id;
public GoogleMap.OnMarkerClickListener init(String id) {
local_id = id;
return this;
}
#Override
public boolean onMarkerClick(Marker marker) {
Intent i = new Intent(MapActivity.this, NextActivity.class);
i.putExtra("obj_id", local_id);
startActivity(i);
return false;
};
}.init(id));

How to get hashmap key and value in java from another function

I have a json parse like this
public class SecondFragment extends Fragment implements OnClickListener {
// URL to get contacts JSON
private static String contestUrl = "http://api.apps.com/contest";
// JSON Node names
private static final String TAG_ITEM_ID = "id";
private static final String TAG_URL = "url";
private static final String TAG_START_DATE = "start_date";
private static final String TAG_END_DATE = "end_date";
// contacts JSONArray
JSONArray foods = null;
// Hashmap for ListView
ArrayList<HashMap<String, String>> foodslist;
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
foodslist = new ArrayList<HashMap<String, String>>();
// Calling async task to get json
new GetContacts().execute();
}
/**
* Async task class to get json by making HTTP call
* */
private class GetContacts extends AsyncTask<Void, Void, Void> {
#Override
protected Void doInBackground(Void... arg0) {
// Creating service handler class instance
ServiceHandler sh = new ServiceHandler();
// Making a request to url and getting response
String jsonStr = sh.makeServiceCall(contestUrl, ServiceHandler.GET);
Log.d("Response: ", "> " + jsonStr);
if (jsonStr != null) {
try {
foods = new JSONArray(jsonStr);
// looping through All Contacts
for (int i = 0; i < foods.length(); i++) {
JSONObject c = foods.getJSONObject(i);
String id = c.getString(TAG_ITEM_ID);
String name = c.getString(TAG_URL);
String email = c.getString(TAG_START_DATE);
String address = c.getString(TAG_END_DATE);
// tmp hashmap for single contact
HashMap<String, String> contact = new HashMap<String, String>();
// adding each child node to HashMap key => value
contact.put(TAG_ITEM_ID, id);
contact.put(TAG_URL, name);
contact.put(TAG_START_DATE, email);
contact.put(TAG_END_DATE, address);
String start_date = (String)contact.get(TAG_ITEM_ID);
// adding contact to contact list
foodslist.add(contact);
}
} catch (JSONException e) {
e.printStackTrace();
}
} else {
Log.e("ServiceHandler", "Couldn't get any data from the url");
}
return null;
}
}
}
I have two function, onCreate and GetContacts. In the end of onCreate it call GetContacts and call this json.
My question is, how can I got the Hashmap value on GetContacts so I can use it on onCreate
So far, I got this to get the value of Hashmap
String start_date = (String)contact.get(TAG_ITEM_ID);
But, its only works on GetContacts.
Anyone can help me?
Thanks Before

There are couple of ways:
Way-1:
Create instance variable (class-level) of HashMap contact and then you can use it anywhere within class inclusing onCreate and getContacts method.
package stackoverflow.q_25034927;
import java.util.HashMap;
import java.util.Map;
public class PassVariable {
private static Map<String, String> contact = new HashMap<String, String>();
public void onCreate() {
//populate contact object as per your logic
getContacts();
}
private void getContacts() {
//Use contact object directly which was pre-populby onCreate method.
}
}
Way-2:
Pass map to the getContacts() method:
package stackoverflow.q_25034927;
import java.util.HashMap;
import java.util.Map;
public class PassVariable {
public void onCreate() {
final Map<String, String> contact = new HashMap<String, String>();
//populate contact object as per your logic.
getContacts(contact);
}
private void getContacts(Map<String, String> contact) {
//Use contact object which is passed as argument.
}
}
On other side, please use cameCasing while naming Java methods or variables. GetContacts is not right, make it getContacts.
For email and address fields, using TAG_START_DATE and TAG_END_DATE is no fun. :-)
String email = c.getString(TAG_START_DATE);
String address = c.getString(TAG_END_DATE);
To answer about #3 below, variable s is not accessible in NotInner class:
package com.test;
public class Test {
static String s = "";
}
class NotInner {
public static void main(String[] args) {
System.out.println(s); //Compilation error: s cannot be resolved to a variable
}
}

You have
List<Map<String,String>> foodslist = ...;
which is filled in the loop.
To get at individual values, iterate:
for( Map<String,String> item: foodslist ){
String id = item.get(TAG_ITEM_ID);
String name = item.get(TAG_URL);
String email = item.get(TAG_START_DATE);
String address = item.get(TAG_END_DATE);
}
Or you write a method for the class where you keep foodslist:
String getAttr( int i, String tag ){
return foodslist.get(i).get(tag);
}
and you can call
String id = xxx.getAttr( i, TAG_ITEM_ID );

So return the data ...
public List<Map<String, String>> getContacts() {
if (foodslist != null && foodslist.isEmpty()) {
return foodslist;
}
foodslist = new ArrayList<Map<String, String>>();
try {
foods = new JSONArray(jsonStr);
// looping through All Contacts
for (int i = 0; i < foods.length(); i++) {
JSONObject c = foods.getJSONObject(i);
String id = c.getString(TAG_ITEM_ID);
String name = c.getString(TAG_URL);
String email = c.getString(TAG_START_DATE);
String address = c.getString(TAG_END_DATE);
// tmp hashmap for single contact
HashMap<String, String> contact = new HashMap<String, String>();
// adding each child node to HashMap key => value
contact.put(TAG_ITEM_ID, id);
contact.put(TAG_URL, name);
contact.put(TAG_START_DATE, email);
contact.put(TAG_END_DATE, address);
// adding contact to contact list
foodslist.add(contact);
}
return foodslist;
}
Though I'm not sure why that variable is called foodslist if it's supposed to contain contacts.
